Finisar Corporation introduced several new product and technology solutions at ECOC, the larger optical communications exhibition in Europe. Finisar will demonstrate the latest form factors, laser technology, and test equipment for high-speed connections in hyperscale data centers, 5G wireless networks, and optical test systems. See these demonstrations and more in Finisar's booth 62 at the RDS Venue in Dublin, September 23-25. 400GBASE-SR4.2 QSFP-DD transceivers for high-speed data centers: Finisar and Foxconn Interconnect Technology are showcasing the industry's first interoperability demonstration of 400G SR4.2 QSFP-DD optical transceivers at the Finisar booth. These IEEE-compliant transceivers use eight fibers and an MPO-12 optical connector which provide a low total cost solution for 400G data rate upgrades using the installed base of multimode cabling deployed for 100G SR4 in data centers today. The IEEE P802.3cm task force has made a baseline proposal for 400GBASE-SR4.2 which includes support for up to 70m on OM3 and 100m on OM4 multimode fiber, aligned with the 400G BiDi MSA. This is the second short-reach 400G multimode transceiver announced by Finisar, following the 400G SR8 OSFP module demonstrated at OFC earlier this year. 100G PAM4 VCSEL technology for hyperscale data centers: Finisar is unveiling the industry's first public technology demonstration of a multimode VCSEL (Vertical Cavity Surface Emitting Laser) transmitting at 100G data rates using PAM4 modulation. This technology demonstration is a critical milestone towards product developments that can enable 800G short-reach optical modules and active optical cables (AOCs) needed for next-generation hyperscale data centers. Traditionally, multimode transceivers and AOCs that utilize VCSEL technology have offered the lowest cost for short-reach interconnect applications, a trend that is expected to continue with 800G+ products that are based on 100G PAM4 per lane. Attendees will be able to observe the optical performance of the prototype VCSEL’s over multimode fiber using a high-speed scope. 5G Wireless Front-haul Ecosystem featuring Tunable SFP28 transceivers: Finisar is showcasing various optical transceiver modules for 5G wireless front-haul networks. Driven by the anticipation of very large volume deployments, wireless front-haul applications will require cost-efficient high data rate solutions. Such applications in 5G networks are expected to require primarily 25G data rates, and Finisar is already offering several products covering 300m, 2km and 10km reaches. For 10km, Finisar provides both duplex and bidirectional transceiver solutions to help customers with optical fiber constraints. For C-RAN applications, Finisar is demonstrating LAN-WDM and O-band CWDM solutions, which enable more efficient wireless front haul networks with a minimum number of optical fibers. As part of its 5G product offering, Finisar is also demonstrating full C-band DWDM wavelength tunable SFP28 modules operating at 25Gb/s over 15km of single mode fiber. These transceivers provide significant advantages over fixed wavelength solutions for carriers upgrading their networks to the latest wireless standards. Leveraging DWDM technology allows more efficient use of the limited installed fiber in the front-haul network. Finisar’s wavelength tunable SFP28 transceivers also provide operational efficiencies and savings over fixed wavelength products. These products will be available with Finisar’s patented Flextune™ wavelength self-tuning functionality.
